Comparing Size 3 And 4 I-Gel Supraglottic Airway Devices in Female Patients
Journal Title: Scholars Journal of Applied Medical Sciences - Year 2018, Vol 6, Issue 5
Abstract
Abstract: The present study aimed to compare the results obtained with size 3 and 4 i-gel supraglottic airway devices in female patients undergoing minor surgery and investigate which is the most suitable size. In the present study, 100 adult female patients undergoing routine minor surgical interventions under general anesthesia were randomized into two groups. For each patient, a standard anesthesia protocol was followed. After adequate anesthetic depth was obtained, the selected i-gel was inserted; the number of insertions, number of attempts, success rate of placement, and hemodynamic response were recorded. Whether the i-gel was placed in an anatomically suitable position was evaluated with a fiberoptic bronchoscope. Then, positive pressure ventilation was administered at a rate that the airway pressure did not exceed 20 mmHg, and oropharyngeal leak pressure was measured. Intraoperative and postoperative complications were also evaluated (after recovery and at the 24th hour). The two groups were similar in terms of the duration of insertion process, number of attempts, oropharyngeal leak pressure, and intraoperative and postoperative complications (after recovery and at the 24th hour) (p > 0.05). The increase in mean arterial pressure after induction was found to be higher in the size 4 i-gel group (p = 0.02). Successful insertion on the first attempt occurred in 100% of size 3 i-gel patients and 82.5% of size 4 i-gel patients (p = 0.015). Optimal insertion verified by fiberoptic bronchoscopic imaging by was seen in 67.3% of patients with size 4 i-gels and 22.5% of patients with size 3 i-gels (p = 0.00). Although patients receiving size 4 i-gels had higher hemodynamic response rates than those receiving size 3 i-gels, optimal insertion was higher for those with size 4 i-gels. The rate of successful insertion on the first attempt was 100% for the size 4 i-gels. The fact that the size 3 i-gel insertion success rate was 82.5% and insertion failure rate was 16.2% independent of the weight formulation recommended by the manufacturing firm suggests that when selecting the correct i-gel size, the patient’s weight should not be the only basis and criterion.
